Designed for the non return-control of a wide variety of fluids that do not attack bronze. For use under conditions where pulsating action
in line causes excessive wear in swing-type valves. Discs are renewable and regrindable; seats are regrindable. Because of flow
characteristics, these valves are generally used in conjunction with globe valves.
Discs
Renewable, regrindable bronze discs made of the highest quality steam bronze for excellent performance under high temperatures. Discs are guided above and below seating by disc stem guides and bottom disc guide lugs to prevent cocking.
Seats
Regrindable, integral. Precision machined to fit taper of discs accurately. Can be reground without removing from line.
Bodies
Proportioned for maximum strength, full flow. Large clearances at ends of pipe threads permit tight joints without pipe ends jamming diaphragms, distorting seat, or choking flow. Made of highest quality steam bronze to resist wear and corrosion.
Caps
Screw over body necks; have long, powerful threads for tight connections. Wide flats for firm wrench grip.
Maintenance
To regrind seats, remove cap and apply screwdriver to slot in top of disc
stem. It is not necessary to remove the valve from the line.
